Since abrasive wear takes place when the abrading material is rough and harder than the surface to be abraded, it can be prevented either by eliminating the hard, rough constituent or by making the surface to be protected harder still. During his 33 year career he has held many different international positions within EagleBurgmann and has been the co-inventor of various patented seal designs. There is no consistent effect of velocity on the coefficient of friction.

The cause of these behaviors was found in the change of the convergent shape. When the ellipticity was varied, the Poiseuille flows parallel and transverse to the entrainment direction were significantly modified and these modifications were quantitatively analyzed for the different cases epub.

The simulation results of the present study indicate that the surface texture can appreciably change the shaft center-line locus and oil film pressure distribution comparatively to the smooth case. The texture arrangements on the bearing surface, the texture number in the circumferential or axial directions, and the texture depth in the radial direction, all of them have significant influences on the static characteristics of a flexible journal bearing ref.: Solving tribology problems in download epub http://old.gorvestnik.ru/library/solving-tribology-problems-in-rotating-machines.

World Tribology Congress: Abstracts. Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology. April 08, 2014 This review is mainly concerned with investigations devoted to periodic contact problems involving frictional effects, which were carried out by scientists from the former Soviet Union and CIS countries. The following class of problems is considered: 2D and 3D problems of frictional sliding contact between elastic and viscoelastic bodies with regular relief; stick-slip contact of bodies with wavy and periodically grooved surfaces; thermoelastic interaction between bodies with regular relief with regard for frictional heating; sliding contact between a surface with regular relief and a viscoelastic layer bonded to a rigid or an elastic foundation; effect of adhesion or incompressible fluid in the gaps on contact parameters in sliding contact between a textured surface and a viscoelastic layer Lubrication Fundamentals, Second Edition (Practical Spectroscopy)

With a favorable concentration, the graphene was dispersive. The PAO2 oil with 0.05 wt % graphene showed better tribological properties than that for the other concentration of graphene additives. It could be used as a good lubricant additive for its excellent tribological characteristics, and the multi-layered graphene can bear the load of the steel ball and prevent direct contact of the mating metal surfaces Tribology in Engineering read online
